The suspension of the rotor was provided by two sets of radial permanent magnetic bearings operating in the repulsive mode. The axial support was provided by jewel bearings on both ends of the rotor. The rig was successfully operated to speeds of 5500 rpm using an air impeller. Radial and axial stiffnesses of the permanent magnetic bearings were experimentally measured and then compared to finite element results. The natural damping of the rotor was measured and a damping coefficient was calculated.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Winfredo Morales\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1289235600\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781289235604\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Bibliogov\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/23\/2013\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 22\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.13lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.69h x 7.44w x 0.05d","brand":"Winfredo Morales","offers":[{"title":"Paperback","offer_id":47611430863103,"sku":"9781289235604","price":14.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_ba54b1d2-c539-4869-beeb-f64490e0fa54.jpg?v=1764513830","url":"https:\/\/www.whiterainbookhouse.com\/products\/permanent-magnetic-bearing-for-spacecraft-winfredo-morales-9781289235604","provider":"WR Book House","version":"1.0","type":"link"}
